I tried putting it on sd and other folders. But this didn't make a difference (working on sd cart looked better in fact) Thanks.

The position within the file where the text was found? The number of occurrences? Show the file with the found text highlighted? I suspect that you're really looking for a way to browse through a text document, including searching. Is that right? If not, then can you describe, in general terms, what you're trying to accomplish? Thanks, Dave

Case-insensitive POS[N] versions: \<< SWAP LCASE SWAP LCASE POS \>> 'POS2' STO \<< ROT LCASE ROT LCASE ROT POSN \>> 'POSN2' STO LCASE (and UCASE) may be obtained from the following post, in direct binary forms as well as source, including even a UserRPL substitute covering many situations: http://groups.google.com/group/comp.sys.hp48/msg/015b461d5c0e9956 LCASE (and UCASE) may also be extracted from this binary package: http://www.hpcalc.org/search.php?query=roldxj Since there is a case-insensitive "find" in the 49G/50G string editor, there must also be some equivalent in ROM, but where? (any flashptrs?) The built-in EDITB, for a string, has FIND, REPL, NEXT Etc. functions (first press NXT, SEARCH) with the aforementioned case-insensitive option. Flag -73 controls whether minifont (vs. "system" font) is used for EDITB.. \<< DUP EDITB DROP \>> may be used as a viewer (preventing changes). [r->] [OFF]

Sounds to me like you're using it to search for exam answers in a text file on your calc -- Dan Field (Graduate Surveyor) "ferroburak" <ferroburak(a)gmail.com> wrote in message news:dc934a32-2205-4e42-a826-ee6d82e18b05(a)d21g2000yqn.googlegroups.com...
